Residential Heating System Cost Calculator

Use this tool to estimate what your annual heating costs would be using different heating systems.

1.       Find the row that best describes your home’s heating system configuration
2.       Update fuel cost and other relevant assumptions (efficiency rating is under “show           details”)
3.   Click “Calculate”
4.       Press Increase/Decrease until Annual Cost matches yours

BTUs per unit - The amount of potential heat energy contained within a measured unit of a given fuel type. A BTU (British Thermal Unit) equals the energy needed to raise the temperature of one pound of water by one degree F.

System Efficiency - Measure of the percentage of potential energy contained in a fuel source that actually gets delivered as heat within a home heating system (i.e., an 85% efficient system wastes 15% of its heating potential).

Distribution Efficiency - Measure of how efficiently heat generated by a source (boiler, furnace, etc.) is distributed throughout a heating distribution system (baseboard, forced hot air, radiant, etc.).

Default electric price is weighted by utility residential load (CMP and Versant only), and based on whole-home heat pump usage for 92 MMBTU/year heat load. Annual Heating Cost represents the added cost to power heat pumps after switching to Versant’s Home Heating Eco Rate and CMP’s Electric Technology Rate.
